APPARATUS POR- TURNING THE LEAVES. 0I" MUSIU.

.To ALL WHoM 1T MAY ooNcERN:

13e it known thnt I, THOMAS GOODIUM, of Providence, in the county of Providence, and State of Rhode Island, have invented a new and useful Improvement for Turning Leaves vci: Music; and I do hereby declare thatthefollowing is a full, clear, and Vexact description of the same, reference being had to the annexed drawings, making a part'of this specification, in which- Y Figure 1 is a perspective view of my invention.

Figures 2, 3, and 4 are detailed parts.

In the accompanying drawings, A, fig. 1', is a fiat strip of wood, ashort distance from one end ofvwhich, and on its front surface, is fastened a cross-piece, B. Each end of this cross-piece 'is provided with e. plate of brass,iextending below its lower edge, and, in connection'with A, forms n clamp, for the purpose of holding my invention on the desk of a piano-forte or an organ. On the back surface of'A are two arms, e and e', having a, spindle, C, 1n'tted to their extended ends, and protruding s. suitable vdistance through e. Fig. 2 is a piece of metal, made tapering, and bent at an angle near its centre, 'called a finger, the largest end of which has a hole, and lits easy onspindle C. I have tive of these fingers on my invention, as shown in lig. 1, but I am not confined to that number, as more or lesscun be used, 'as desired. D, iig. I, is a piece of metal, fastened to the upper end of A, used'as a rest, and for the metal fingers to slide upon. F, fig. 1, is a strip of brass, the ends made curving, and on its under surface is a ratchetprojection, as shown in iig. 4. The ratchet-edge is raised the same thickness as one of the-metal lingers, to lit and move only one 4finger at a time when innse. F is fastened to a lever, and the lever counectedto spindle C by a hinge-joint, above the metal fingers. h, lig. 3, is a piece of wire, bent atan angle, for the purpose of holding sheet-music, it being applied to my invention by sliding the short bend into a socket, at the upper end of A, fig. 1. This socket is drilled through inte the arm c', so that the sho-rt bend of wire can be pressed iu the distance required, to hold different thicknesses of music. On the lower end of spindle C is a-coiled `sp'ringpone end connected to arm e, the opposite end of which is attached to e. lever, I. This lever is fastened to spindle C 'with a set-screw.

To use my invention,- a string or cord is fastened to lever I. The oppositeend of string is connected to a {cotti-enfile, near the floor. The-taper ends of the fingers are placed between the pages of music, and, when desired, the foot-treadle is worked by the foot, drawingthe lever I in the direction of the arrow, iig. I. This lever I` being fastened to spindle C, causes it to turn in connection with F, upon which the ratchet-edge comes in contact with the top or first finger, moving it to the left, and opening one leaf or sheet of music.- By raising the foot from the treadle, the coiled spring on spindle C draws the connections back to their places, thus bringing F in position to act on the second finger, as the first finger is not carried back. To prevent the spiral spring from drawing too far, I have madeA a ring on spindle C, with a. set-screw, to bring up against a wire stud on arm e. By operating the treadle, all the fingers can be moved one by one, as the number may be.

The great advantage of my invention is, the player can open his music without removing his hands from the keys of his instrument, as F is fastened to a lever, and this lever connect-ed to spindle, C, by a hinge-joint. Different number of ngers can be used, for F will raise or lower, to adapt itself to them.

What I claim as my invention, a nd wish to secure by Letters Patent of the United States, is-

The ratchet-plate F, hinged to and operated by the spindle and lever I, in combination with the fingers, for turning over the leaves of music-books, substantially as shown and described.
